For example, traveling 50mpg for 5 miles, coasting to a red light in neutral the motors rpms will drop to roughly 200 and last maybe a second or two. Then... the idle jumps back to where it belongs. This occurs even when the motor is cold and idling high, but only after being driven.

Yes, I've checked Haynes (cant get a Cliton) and I have checked the vacuum lines. Two of them were faulty and replaced (MAF and FPR.) I did; however, notice that after I changed the radiator and flushed and filled it, it didnt do it as BAD, but it still boggs.

Any suggestions? PM me if youd like. Otherwise I'll try and find a "tuner" shop in this crusty white/redneck state.

oh sh1t you in ohio? im sorry, i was born there. check all of your accessories that are connected to the crank pulley with belts (AC, PS, ALT...) . if any of those are starting to lock up, it will work fine while driving and there is force to spin them, but when you stop and it idles down there is less force and the resistance of the accessories pulley locking up will cause it to bog down. could also be from the belts being to tight, never had that happen though. i just had a alternator start to lock up and it bogged the motor down, and evently wouldnt even let it start.
